Irreligion in Montenegro refers in its narrowest sense to agnosticism, atheism, secular humanism, and general secularism. Increase of the number of irreligious people is usually interpreted by the modernization marked with tendency of secularization and the progress of science and technology that directly affect human society.
The majority of Montenegro's population, 98.69%, declares to belong to a religion, though observance of their declared religion may vary widely.

Montenegrins are mostly Orthodox Christians; however, the population also includes Catholics, Muslims and irreligious people. The Montenegrin language is the official language of Montenegro.
